  • Purpose: This study is to investigate if the effectiveness training program, suggested by Gordon(1970), could help these nursing students with the problems of interpersonal relationship and self-identification. Method: This study was designed using nonequivalent control group protest-posttest design. The subject for this study were thirty nursing students. Fifteen nursing students of the experimental group experienced the Effectiveness Training for 8 weeks (3 hours/week). The effect of Effectiveness Training was measured using Relationship Change Scale devised by Lee, H.D. & Moon, S.M.(1979) and Ego Identity Scale devised by Dignan(1965) which was translated by Seo, B.Y.(1975) Pretest data were collected by the researcher from both experimental and control group before training. After the end of eight weeks training, posttest data collected from both experimental and control group. Samples were analyzed using SPSS PC+. Result: 1. The first hypothesis, "level of interpersonal relationship of the experiment group after 8 weeks will be significantly higher than that of the control group"(z=-1.965, p=.049)was supported. 2. The second hypothesis, "level of ego-identity of the experimental group after 8 weeks will be significantly higher than that of the control group"(z=-2.191, p=.028)was supported. 3. The third hypothesis, "level of interpersonal relationship of the experiment group will be significantly higher than that of the control group after 4 months of training"(z=-.634, p=.238)was not supported. 4. The fourth hypothesis, "level of ego-identity of the experimental group will be significantly higher than that of the control group after 4 months of training"(z=-.292, p=.642)was not supported. Conclusion: The Effectiveness Training can be considered as an effective method of nursing students's interpersonal relationship & ego-identity, because it was proved to help nursing students increase level of their interpersonal relationship & ego-identity but it was needed to reinforce for continuing of the effect of the interpersonal relationship & ego-identity.

  • The basic purpose of this research is to analyse a relationship between the integration level of AMT(ILAMT) and manufacturing performance (cost, quality, flexibility, delivery) and to identify the moderating effects of organizational structure in the relationship. First research question(hypothesis 1) was to examine the relationship between ILAMT and manufacturing performance. We tested this question using simple regression analysis. All of the correlation were positive and significant at the level of 1%(two-tail test). Therefore, hypothesis 1 was supported by the results. It means that firms that have high ILAMT are to exhibit high level of all manufacturing performance(cost, flexibility, quality, delivery). Namely, It is that the integration of AMT can solve the trade-off among manufacturing performance. Second research question (hypothesis 2) was to identify the moderating effects of organizational structure on the relationship between ILAMT and manufacturing performance. we tested this question using moderated regression analysis. According to the results, hypothesis 2 was partially supported. In other words, formalization and decentralization were accepted, but complexity was rejected. It means that firms with high ILAMT and an organic organizational structure are more likely to exhibit high level of manufacturing performance. To the practitioners, this research provided the answer to what they ought to do make AMT work in their organizations. To increase the effectiveness of AMT, first of all, they should take notice of the importance of integrated use of AMT, and the implementation of AMT should take into consideration the characteristics of organizational structure manufacturing strategy so that the effect of AMT may be multiplied by using AMT.

  • The purpose of this study was to investigate the effects of students' prior knowledge on scientific reasoning process performing a task of controlling variables with computer simulation and to identify a number of problems that students encounter in scientific discovery. Subjects for this study included 60 Korean students: 27 fifth-grade students from an elementary school; 33 seventh-grade students from a middle school. The sinking objects task involving multivariable causal inference was used. The task was presented as computer simulation. The fifth and seventh-grade students participated individually. A subject was interviewed individually while the investigating a scientific reasoning task. Interviews were videotaped for subsequent analysis. The results of this study indicated that students' prior knowledge had a strong effect on students' experimental intent; the majority of participants focused largely on demonstrating their prior knowledge or their current hypothesis. In addition, studnets' theories that were part of one's prior knowledge had significant impact on formulating hypotheses, testing hypothesis, evaluating evidence, and revising hypothesis. This study suggested that students' performance was characterized by tendencies to generate uninformative experiments, to make conclusion based on inconclusive or insufficient evidence, to ignore, reject, or reinterpret data inconsistent with their prior knowledge, to focus on causal factors and ignore noncausal factors, to have difficulty disconfirming prior knowledge, to have confirmation bias and inference bias (anchoring bias).

  • This study performed to examine the genuineness of Kyung-Jong's poison hypothesis which was the one of the biggest topic in the history of Joseon Dynasty. Kyung-Jong's poison hypothesis is that Kyung-Jong who was the 20th king of the Joseon Dysansty was poisoned by the next king Young-Jo who became the 21st king. This theory was hyphosized by Sim-Yoohyun and was widely known in the 4th year of Young-jo through the revolt. Kyung-Jong suffered with severe diarrhea for 5 days which finally took his life away right after he had have marinated raw crab and persimmon. Some insist the poison must had been in those foods. However, the symptoms that Kyung-jong had were not matched with the poisons which used in those days and also poison was not the reasonable way of murder, so it is hard to say there is little possibility of poison. On the other hand, considering of Kyung-jong's health, marinated raw crab and persimmon could result of severe diarrhea. In the mean time, the possibility of Young-Jo's intention of killing Kyung-Jong is very low. Rather, he blame the royal doctors who scout the outside doctors, because he believed that it led Kyung-jong's death since the treatment was chaotic with all those different doctors. Even after the Kyung-Jong's death, Young-jo was always strict to scout the outside doctors and missed Kyung-jong consistently. On this basis, it is hard to say that king Kyung-Jong was murdered by poisoning.

  • The purpose of this study was to develop the analytic framework of Creative Problem Solving(CPS) for elementary school science textbook. For this purpose, we developed the framework based on the theories of problem, definition of problem solving and various kinds of CPS model. The six elements of the framework for content analysis were extracted through theoretical examination: problem introduction, problem statement, solution thinking, formulating hypothesis, testing hypothesis, and assessment. The developed framework was applied to the extbooks for the 5th and the 6th grades 1st semester in elementary science textbook of the 7th national curriculum. The results of this study were as follows: 1. The scores of the framework for content analysis in the 5th grade were slightly higher than those of the 6th grade, but there were no significant difference. 2. The comparison of the scores between the elements of the framework was found that the scores on the elements of testing hypothesis and formulating hypothesis were higher than those of the other elements. 3. The comparison of the scores between the units was found that the scores of the framework for the 9th unit (“trip of water”) of the 5th grade were higher than those of the other units, which were presented lower level than 1.0 (50.0%) score of the framework. 4. The comparison of the scores between the intensive course and the regular coures in the 6th grade textbook was showed that the scores on the intensive course were higher than the basic course. In conclusions, it was found that the problem introduction and problem statement in the textbook should be amended, and that various information and activities should be presented in the textbook.

  • The process of physical therapy uses a problem-solving approach to enhance a patients's functioning status. The International Classification of Functioning, Disability and Health(ICF) is the common concept for the functioning in the world. Physical therapists require the ability to identify problems, formulate hypothesis, and plan intervention strategies through clinical reasoning. In the clinical process, physical therapists need to use standard and common languages in speech and in documentation. The purpose of this study was to suggest the process of making strategy for efficient intervention, examining and evaluating the functional problem of the person with stroke using ICF tools. For the first step in this process model, therapists could list the information relating to functional problems used by the ICF Core set and then could identify the interaction among the problems using the ICF assessment sheet. For the next step, therapist is needed to make the hypothesis and hypothesis testing, and then set a primary functional goals and therapeutic goals in detail after prioritizing the problems to be managed based on the problem list. Finally, after setting the identified problems as the purpose of intervention through the hypothesis testing, therapist could do some intervention after making a plan to solve these problems, and find out the outcomes using the ICF evaluation display. This report illustrates how to apply the process based on ICF concept into physical therapy practice. Making a decision for the most efficient intervention requires that therapists use the clinical reasoning process based on ICF concept.

  • Purpose - Most past studies related to this focused on the physical attractiveness of service employees, but this study emphasizes the social attractiveness and not just the physical attractiveness of employees. Therefore, the purpose of this study is to first categorize attractiveness as physical attractiveness and social attractiveness and to examine the impact of physical attractiveness on social attractiveness for service industry employees. Secondly, this study aimed at verifying the impact of physical attractiveness and social attractiveness on interpersonal trust. Third, it aimed at revealing the impact of interpersonal trust on customer satisfaction, as well as satisfaction on loyalty. Research design, data, and methodology - Questionnaires were distributed to customers that used beauty salon services, among the various service industries, to verify the hypothesis of this study. Also, hypothesis was analyzed with the structural equation method using Amos 20.0. Results - When presenting the results on verifying the research hypothesis, it was found that physical attractiveness had a positive impact on social attractiveness. Second, while physical attractiveness did not have a positive impact on interpersonal trust, social attractiveness was found to have a positive impact on interpersonal trust. Such results show that in forming interpersonal trust, social attractiveness was more important than physical attractiveness for service industry employees. This result is in contrast with the results of past studies, but it is different in that previous studies suggested only physical attractiveness and did not present social attractiveness in the hypothesis. Third, it was found that interpersonal trust had a positive impact on satisfaction, while satisfaction did not have a positive impact on loyalty. Conclusions - The biggest implication of this study is that it presented social attractiveness, which was rarely dealt with in past studies. Also, this study is significant in that it examined the relationship of physical attractiveness and social attractiveness. The results of this study show that in the service industry, the role of human elements such as service employees is important and that in addition to physical attractiveness, social attractiveness in the course of interaction such as communication with customers can also be an important strategic element.
